%% Change Projection Updating Meridian and Parallel Labels % This example shows how to change the projection of a map and update the % meridian and parallel labels. %% % Create a Mercator projection with meridian and parallel labels. % Copyright 2015 The MathWorks, Inc. axesm mercator framem on; gridm on; mlabel on; plabel on setm(gca,'LabelFormat','signed') axis off %% % Get the default map and frame latitude limts for the Mercator projection. % Note that both the frame and map latitude limits are set to 86 degrees % north and south for the Mercator projection to maintain a safe distance % from the singularity at the poles. [getm(gca,'MapLatLimit'); getm(gca,'FLatLimit')] %% % Switch the projection to an orthographic azimuthal. setm(gca,'MapProjection','ortho') %% % Specify new locations for the meridian and parallel labels. setm(gca,'MLabelParallel',0,'PLabelMeridian',-90, ...
